RIVM contributes to the development of the European methodology for water quality standard setting. It is proposed to adapt the methodology at several points to improve the derivation of the standards. <br> <br>Chemical substances may impair surface water quality and harm human health and ecosystems. The European Water Framework Directive (WFD) sets maximum concentrations for several compounds. These standards should also ensure that water quality is sufficient to protect against adverse effects of consuming contaminated fish products. <br> <br>The present derivation of human-health based water quality standards uses a default fish consumption of 115 gram per person per day. RIVM concluded previously that this value is not well underpinned. Data of the European Food and Safety Authority (EFSA) show that fish consumption varies among member states. Within countries large differences exist between people that particularly like fish and others who consume little. <br> <br>RIVM proposes to use a default fish consumption of 1.63 gram per kilogram bodyweight per day. The calculation takes account of member states with a high proportion of fish consumers. In this way, European-wide quality standards will also protect people from countries with a higher fish consumption. Expressed on a person-basis, the new value is similar to the old default but it is well documented. Member state specific fish consumption data are relevant to evaluate the actual risks at locations where the European standards are exceeded. <br> <br>The methodology also takes into account that other exposure routes contribute to a high extent to the total intake of a compound by humans. The contribution of fish is set to 20 procent. Where possible, the actual contribution of fish to the total intake should be taken into account to better estimate the risks of this exposure route for human health.<br>
